Understanding Human Body Tissues

The human body has fascinated everyone who took just a few minutes to understand the complex structure that makes man stand on their two feel and capable of doing what they do. The human body, a collection of four different types of human body tissues, has enabled men to stand as one of the most intelligent creature that evolved to be the maintainer of all species on earth. Everything about human is interesting, how their body work, how they think, how they live and manage their society etc, have fascinated men into dedicating years of study about them. But at the core of it all the study of human body tissue.The complex structure of human body is in fact made up of only four types of human body tissues, each with their distinctive structure, properties and functions. The epithelial tissues, the outer layer of the skin, act as a barricade protecting the much softer inner structures and organs. They are the primary defense mechanism of the human body, resisting penetration of harmful bacteria, viruses and materials from entering the body.

Understanding Human Body Tissues

The connective tissue, like the ligaments, inner layer of the skin etc, adds support and strength to the human body. These type of human tissues contain fibrous strands that adds strength to the body.The muscle tissues, a specialized tissue, can contract and relax either voluntarily or involuntarily. These tissues contain two types of protein called actin and myosin in layers that can slide over each other enabling the muscle to move. Some of these tissues are trained to add more strength to them and hence the body.Nerve tissues are the most complicated form of human body tissues. These tissues carries message from one different parts of the body via electrical current to the central and spinal nervous system that in turn contains more nerve. These nervous systems are responsible for the functioning of the entire body.
